Abstract

PURPOSE: To transmit a certain rotary torque and to give a stabilized tension to a member by exerting a rotary energizing force on a roller via the magnetic coupling linked at least one part of a pair of rolls interposing the member giving a tension.
CONSTITUTION: A roller 11 receives a rotating power from a motor 16 via a magnetic coupling 15 at its rotary shaft 13 and is rotated, Then, a wire 19 is located between rollers 11, 12 to close them. Accordingly, the rotating power of the roller 11 is transmitted to the wire 19 and the rotation of the rollers 11, 12 stops at the time when a tension is given on the wire 19. However, due to the rotary power of the motor 16 being transmitted to the roller 11 via the coupling 15 a specified tension is continuously given on the wire 19. At this time, the cups 15a, 15b of the magnetic coupling 15 transmit a rotary torque but no rotation. Consequently a constant stabilized rotary torque can be transmitted.
